(c) The electrical system and other function groups are candidates for
cost reduction because their value indexes are less than 1.
8-36 The traditional focus of cost management has been only on manufacturing
processes. Under this approach, pre-manufacturing costs, such as research
and development, and post-manufacturing costs, such as service, are
considered period costs, and companies expense them in the period
incurred. Thus, these costs are in no way linked to individual products.
Traditional accounting procedures and the way that many organizations
have been separated by department or function (e.g., design engineering,
manufacturing, marketing, logistics, installation and postal service), often
lead managers to focus myopically on their own department’s costs. In
particular, for the manufacturing function, defining product costs as those
solely related to the manufacturing process ignores many costs associated
with the entire life cycle cost of a product.
Understanding the total life cycle costs (TLCC) of a product or service, or
the product costs incurred before, during, and after the manufacturing cycle
is critical, as decision makers can more completely analyze and understand
what creates product costs. For example, if a company can reduce a
product’s design and development costs at the pre-manufacturing stage, it
also is possible to reduce all other subsequent product-related (downstream)
costs such as manufacturing and service-related costs. A TLCC system
provides information for managers to understand and manage costs through
a product’s design, development, manufacturing, marketing, distribution,
maintenance, service, and disposal stages. The total life approach is also
known as managing costs “from the cradle to the grave.”
8-37 Gregoire Grant is shortsighted. The manufacturing cycle of the total-life-
cycle costing approach is only one of three major stages of the product life
cycle concept. The other life cycle concepts are research, development and
engineering, and post-sale service and disposal. While each concept is
useful within its respective functional area, from a total-life-cycle costing
(TLCC) perspective, it is important to integrate the concepts and to
understand them in their entirety. Such integration allows managers to see
the big picture and to manage whole-life product costs in a comprehensive
fashion. For example, poor decisions in the research development and
engineering stage may lead to much higher costs in the manufacturing and
post-sale service stages. Thus, it is in Gregoire’s best interest to understand
what is occurring in the research development and engineering stage.
